2011-02-17	ARM: P2V: separate PHYS_OFFSET from platform definitions	Russell King	1	-1/+1
	This uncouple PHYS_OFFSET from the platform definitions, thereby facilitating run-time computation of the physical memory offset.

2010-07-27	ARM: 6225/1: make TCM allocation static and common for all archs	Linus Walleij	1	-43/+48
	This changes the TCM handling so that a fixed area is reserved at 0xfffe0000-0xfffeffff for TCM. This areas is used by XScale but XScale does not have TCM so the mechanisms are mutually exclusive. This change is needed to make TCM detection more dynamic while still being able to compile code into it, and is a must for the unified ARM goals: the current TCM allocation at different places in memory for each machine would be a nightmare if you want to compile a single image for more than one machine with TCM so it has to be nailed down in one place.

2010-07-18	ARM: 6223/1: support multiple TCM banks	Linus Walleij	1	-22/+46
	CPUs v6 and up support multiple TCM banks, for example an ITCM of 8k is supplied in two 4k banks. This makes the TCM work on the 1176JZF-S devchip. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-07-18	ARM: 6222/1: add memory types for the TCMs	Linus Walleij	1	-3/+2
	The earlier TCM memory regions were mapped as MT_MEMORY_UNCACHED which doesn't really work on platforms supporting the new v6 features like the NX bit. Add unique MT_MEMORY_[I\|D]TCM types instead.

2009-09-15	ARM: 5580/2: ARM TCM (Tightly-Coupled Memory) support v3	Linus Walleij	1	-0/+246
	This adds the TCM interface to Linux, when active, it will detect and report TCM memories and sizes early in boot if present, introduce generic TCM memory handling, provide a generic TCM memory pool and select TCM memory for the U300 platform.
